TOP 10 SPACE YOUTUBE CHANNELS 2018

Today, we discuss the possibility of humanity being alone in the galaxy or perhaps even the greater universe. We consider just how improbable our existence is by evaluating both the number of potential sites for life within our galaxy alone as well as the probability of abiogenesis occurring elsewhere. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by David ►Share this video: https://youtu.be/yyVJkbUbzxY Music: “Cylinder Five” by Chris Zabriskie “Cylinder Eight” by Chris Zabriskie “Stories About the World That Once Was” by Chris Zabriskie

SpaceX will launch 57 Starlink satellites and 2 BlackSky Global satellites on their Falcon 9 rocket. It’s launching no earlier than August 7, 2020, from Launch Complex-39a (LC-39a) at Kennedy Space Center, Florida. Starlink 9, is the ninth operational launch of SpaceX’s Starlink communication satellite constellation. Want to learn more about today’s launch?

Starting off TMRO:News this week Ryan takes us on a hop, skip, and a splash in his SpaceX Update. Jared covers RocketLab and Virgin Orbit finding their respective anomalies, along with Virgin Galactic unveiling the customer cabin of SpaceShipTwo. An independent safety panel convened by NASA aims squarely at Boeing's Starliner, but SpaceX also gets some stern words as well. Space Traffic sees a pair of launches: one Mars rover, and a set of Russian comsats. Dr. Tamitha Skov delivers this week's Space Weather with the northern hemisphere of the Sun beginning to pick up activity. Jared wraps us up with some info on upcoming Ariane 5 flight tests that Arianespace will run to accommodate the James Webb Space Telescope. And of course: thank you all for your support!

In this week's questions show, I consider what the benefits might be to humanity if we discover that we aren't alone in the Universe. How long did Mars planetary dynamo take to turn off? Could we find and repair the lunar rovers? 00:00 Start 00:12 Would extraterrestrial life have any impact on us? 03:01 When did Mars shut down? 05:16 Could the rovers be repaired? 07:05 Would an ejected star take its planets with it? 08:54 Dangerous to go to Mars at the same time? 10:19 Is there any way to go faster? 13:37 Should the smallest black holes already have evaporated? 15:48 Shouldn't Voyager be coming back? 17:15 Could there be life inside Jupiter? 18:50 Does the Sun have a binary black hole partner? 19:57 Aren't I on vacation?

Lighthouses have helped safely guide mariners for centuries. As space explorers consider traveling to far-flung destinations, could pulsars provide them with similar guidance? » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com As NASA sets its sights on distant planets, astronauts will need a way of orienting themselves in space. Here on Earth, we use the satellite-based GPS that carry atomic clocks that provide extremely accurate time, which gets used by your phone or car to help calculate your position. And while GPS works just fine if you’re on Earth or close to it, the signal weakens once you go beyond its range. Historically, NASA has primarily used the Deep Space Network to track missions beyond Earth’s orbit. The three ground stations are approximately 120 degrees apart, and they beam up radio waves to a spacecraft and log details as the signals return. Navigation data is calculated on Earth and sent back, helping ground control keep missions on the right path. But if that radio link with Earth is lost, a spacecraft can find itself adrift. And so we need a better solution, like if a spacecraft could navigate independently, without ground control. Enter: Pulsars. Find out how neutron stars, pulsars, and a piece of equipment called the Neutron Star Interior Composition Explorer, or NICER, can help spacefaring explorers navigate space more effectively in this Elements. #spaceexploration #NASA #astronauts #GPS #space #science #seeker #elements Read More: Future Space Travelers May Follow Cosmic Lighthouses https://www.nasa.gov/mission_pages/station/research/news/future-space-travelers-may-follow-cosmic-lighthouses-sextant-results "An X-ray telescope on the exterior of the space station, the Neutron star Interior Composition Explorer or NICER, collects and timestamps the arrival of X-ray light from neutron stars across the sky." Fast-spinning pulsars can act as the universe's timekeepers http://www.bbc.com/earth/story/20150805-the-most-accurate-clocks-in-space "Millisecond pulsars offer clues. The pulses allow scientists to precisely determine the pulsars' orbits and thus their masses - crucial data that theorists need to constrain and devise new hypotheses." Pulsars at 50: Still going strong https://astronomy.com/bonus/pulsars "When astronomers initially stumbled upon these rapidly pulsing beacons in 1967, they thought they had found ET. The truth was almost as shocking." ____________________ Elements is more than just a science show.
